Rose plant named &#39;RNF Cream 01&#39;

ABSTRACT

A new and distinct rose plant having a strong fragrance and creamy yellow-colored flowers.

Botanical classification: Rosa L.

Varietal denomination: ‘RNF Cream 01’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of roseplant known by the varietal name ‘RNF Cream 01’. The new variety wasdiscovered in April of 2010 in Gifu, Japan. The new variety is theresult of a planned breeding program between Rosa L. variety ‘GoldBunny’ (female parent, U.S. Plant Pat. No. 4,625) and an unnamed andunpatented Rosa Rugosa variety (male parent) from the breeder's owncollection. ‘RNF Cream 01’ has a different flower color than its femaleparent. Additionally, ‘RNF Cream 01’ exhibits a fragrance like its maleparent, but differs from its male parent in its actual fragrance. When‘RNF Cream 01’ is compared to Rosa L. ‘Evera 107’ (U.S. Plant Pat. No.16,957, Japanese Patent No. 17880), the varieties are similar in flowercolor, not having eyes on their flowers, and in that they exhibit doubleflowers. However, when compared to ‘Evera 107’, ‘RNF Cream 01’ has alarger flower size, different number of petals, and exhibits afragrance. When generally compared to other rose varieties known to thebreeder, the new variety differs in its strong fragrance, its type offragrance, and in flower color. ‘RNF Cream 01’ has been trial and fieldtested and has been found to retain its distinctive characteristics andremain true to type through successive propagations.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of thenew cultivar. The data which defines these characteristics werecollected by asexual reproductions first performed via cuttings in Mayof 2011 carried out in Gifu, Japan. Plants of the new variety were grownin a greenhouse under natural light in 15 cm pots with peat mosssubstrate and with the assistance of heaters in the winter. The colorreadings and measurements were taken indoors in a greenhouse undernatural light on one-year-old plants grown in containers. Colorreferences are primarily to the R.H.S. Colour Chart of The RoyalHorticultural Society of London.
